Urban Design and Landscape Plan

• Purpose of the UDLP

• UDLP includes:

• Design principles / colours and materials

• Bridges and structures

• Landscaping / land-use reinstatement

• Shared path (pedestrian and cycle facilities)

• Roadscape elements

• Maintenance considerations

Colours and materials

Planting and trees

• Coastal experience - native coastal species

• Eco-sourced from Tamaki Ecological District

• Appropriate ecotypes

• Reference to existing vegetation

• Pohutukawa at gateway locations

Planting and Trees

Planting and trees

• Wide range of experts review construction activities

• Pre-clearance and ongoing inspections for lizards, vegetation, trees and archaeology

• Ongoing monitoring of earthworks compliance, contaminated soils, noise, air quality, marine ecology and birds

• Stormwater, erosion/sediment control, coastal area protection established prior to works commencing and regular inspections

• Monitoring results to be issued

Rosebank Park Domain access road

• Design refinements to the approved Domain access road works - Retaining wall adjacent to SH16 and shared

Proposed embankment planting

Oakley Boardwalk

• 280m long concrete structure

• 3m wide between handrails

• Two-way cycle and pedestrian movement

• 1.5m high noise wall

Rosebank Boardwalk

Current design – new boardwalk

Existing timber boardwalk

Alternative Design – fill embankment

Alternative Design – fill embankment

Alternative Design – fill embankment

Benefits compared to a 3m wide timber boardwalk: • Improved amenity and user experience from consistent width

• Improved sightlines for users with no balustrades

• Continuation of asphalt surface along path

• Constructability benefits – no temporary embankment for piling works in marine area (which is later removed)

• “Whole of life” solution - better design life and reduced maintenance requirements

Alternative Design - next steps

• Obtain feedback on the alternative design

• Changes to statutory approvals:

- Coastal consents

- Marine Reserves Act Authority

• Lodge applications with Auckland Council (consent changes) and the Department of Conservation (Marine Reserves Act Authority changes)

Environmental monitoring - overview

• Broad range of experts review construction activities

• Pre-clearance and ongoing inspections for lizards, vegetation, trees and archaeology

• Stormwater, erosion/sediment control, coastal area protection established before works begin and regular inspections

• Ongoing monitoring of earthworks compliance, contaminated soils, noise, air quality, marine ecology and birds

• Monitoring results to be issued to CLG

Bird monitoring and management

• Monthly bird monitoring results of high tide roost at Harbourview-Orangihina (Te Atatu Pony Club), counting 12 different types birds:

• Avian quarterly report: Causeway Alliance’s construction yard / office area is having no impact on roosting birds

Month Pre-establishment (2010) Current (2013)

May 276 614

June 470 588

July 286 342

Bird roosts at Causeway Bridge

• Provide alternative roost for birds during construction works near the Causeway Bridge

• Two sites chosen south of Causeway Bridge, in channels

• Install floating pontoons, size approx 3m x 4m

• Monitoring by our avian expert

Tree assessment and timber use

• Tree assessment and schedule of trees for removal issued to CLG for feedback on 29 July 2013

• STEM (Standard Tree Evaluation Method) assessment by arborist identifies amenity trees (higher value trees)

• When amenity trees cannot be retained they are replaced

• No requests received for timber for ‘heritage’ use

• Requests for timber use by local schools and Te Atatu Pony Club
